Applications:
Plastics and Polymers: Titan Yellow is employed in the coloring of plastics and polymers. It can be added during the manufacturing process to provide a desired yellow color to plastic products, such as toys, packaging materials, automotive parts, and household goods. The dye’s resistance to heat and chemicals ensures that the color remains stable under various conditions. Textile Industry: Titan Yellow is extensively used in the textile industry as a colorant for dyeing and printing textiles. It imparts vibrant yellow shades to fabrics, including cotton, silk, wool, and synthetic fibers. Its good compatibility with different textile materials and excellent colorfastness properties make it a popular choice for achieving consistent and durable yellow hues. Paper and Stationery: Titan Yellow is used in the paper industry for dyeing and tinting paper products. It can be incorporated into the paper pulp to achieve different shades of yellow, enhancing the aesthetic appeal of papers, envelopes, stationery, and other paper-based materials. Ink Production: Titan Yellow is also utilized in the production of inks, including solvent-based inks. It serves as a colorant, providing a yellow hue to printing inks used in various applications, such as packaging, labels, and graphic arts. Other applications: Titan Yellow may find use in a range of other industries and applications. For example, it can be employed as a colorant in paints, coatings, and pigments, contributing to the creation of yellow shades in architectural coatings, industrial paints, and artistic materials.

Trypan Blue is an azo based, hydrophilic, tetrasulfonated blue acid dye widely utilized for assessing cell viability. As an easy method to determining the viability of cells, Trypan Blue will stain dead cells with permeable membranes blue, while the dye is excluded by most living cells and their intact membranes thereby allowing visual determination of living versus dead cells. Although Trypan Blue is predominately used for assessing cell viability of cultured cells, other applications for this dye have been reported. In rat abdominal organ slices Trypan Blue has been utilized to determine cell viability as well as islet cell cluster cell viability from caprine pancreatic samples.
